Gnarly

Imagine getting four stroke power from your two stroke...that would be FMF’s Gnarly! Big low end power and brawny construction make the Gnarly the strongest, best performing off-road pipe on the market. But the real meat behind the muscle is the material. Ultra strong 18-gauge U.S. steel makes this the toughest pipe in our line. Strong and rugged, this aggressive pipe dishes out handfuls of low-end torque with the mid range pull needed for the rigors of the off road domain. This makes the Gnarly an excellent off-road pipe and superb for tighter MX tracks and trails. If you like to ride a gear higher or just prefer tons of low-end grunt, this is the pipe for you.

The FMF Gnarly pipe focuses on increasing the lower RPM horsepower and torque to get you out of the toughest terrain. When looking to add 4-stroke tractor like torque to your 2-stroke and you need a pipe to withstand the harsh elements, this is the pipe for you.

Nickel plating is an FMF trademark and has been ‘copied’ by everyone making it the most imitated expansion chamber in the world.
